I heard that heating foods in soft plastic containers is dangerous -- that carcinogens can leak out into the heated food. This is less likely to happen with hard plastic containers, however. Single-use plates and bowls (like one gets in the frozen section at the grocery store) are okay to heat up though -- once. They should be recycled or thrown away after that though and not used to reheat food in a microwave.

Q:why use plastic canvas yarn?

This is one time that I recommend Red Heart Supersaver Yarn. It is fantastic for working with plastic canvas: It's thick, wear-resistant, and holds its shape.* It comes in a ton and a half of colors, so you can find whatever color or blend your heart desires including sparkly ones. It's cheap. The only drawback is, if you just need a little bit of a color, you will have a lot of yarn leftover. Then, use plastic canvas yarn. *I made plastic canvas/Supersaver Christmas tree ornaments in 1991 that have been used on trees by 5 families every year since and stored in a variety of attics and unheated garages between holidays. They still look new.

Q:why is my cat obsessed with licking plastic?????

OMG!!! My cat actually chews on it and swallows plastic! Weird, but i read thru your answers and now i know why to. LOL, heehee.

Q:Plastic guns with wooden bullets and metal detectors?

No such thing. You were bam-booze-eld. The most plasticized gun made still has as much metal as a small revolver. I think you read this in a novel.

Q:How to get plastic oxidized ?

You can expose them to bacterial or fungal enzymes. That is an extremely broad category and they are likely to have some effect under certain circumstances. You can expose it to a strong oxidizer like ozone. Some would form from lightning strikes. It would probably take hundreds of years to seriously degrade some plastic that way. Some plastic would be seriously affected by some powerful chemical oxidizer. It would be unusual to find natural oxidizers more active unless you include the ionizing effects of UV light on the oxidizer itself. It may become a free radical and become far more reactive. Most of that would probably involve making compounds that are soluble in water so chemicals are leached away.

Q:What is the history of biodegradable plastics?

Biodegradable plastics are plastics that will decompose in the natural environment. Biodegradation of plastics can be achieved by enabling microorganisms in the environment to metabolize the molecular structure of plastic films to produce an inert humus-like material that is less harmful to the environment. They may be composed of either bioplastics, which are plastics whose components are derived from renewable raw materials, or petroleum-based plastics.

Q:Do You Think Plastic Bags Should be Banned?

Banning plastic bags is probably going to be counter productive, because they do have their uses. However, plastic is currently seeing serious abuse. Recycling programs don't work because people won't even put the plastic in the trash let alone separating them for recycling purposes. If people in the U.S. would purchase fabric carrying bags, which they re-use each time they visit the supermarket, we'd be on par with our European cousins who currently have to bring their own bags to the supermarket, because stores do not hand out bags. And we could save the lives of more whales, seals and other marine life.

Q:What is the average salary of a plastic surgeon?

In Canada, Annual earnings for plastic surgeons vary depending on experience, the number of hours worked, and the type of procedures they do. Most plastic surgeons earn between $70,000 and $375,000 a year. However, this number does not take into account their expenses, such as staff salaries and the purchase of equipment and insurance. It also does not include the money they make from performing cosmetic procedures. Cosmetic surgery, such as facelifts, is not covered by the government, but many people are willing to pay the costs of such procedures themselves. Earnings from these procedures can greatly increase a plastic surgeon’s income. In addition to their salaries, most plastic surgeons who work for medical organizations such as hospitals receive benefits. These usually include paid vacation and sick days, pension plans, and health and life insurance. Surgeons who work for themselves must provide their own benefits.

Q:What's the use of plastic?

PET film, PET is mainly used in the plastics industry, film and bottle, and film can be used as packaging, decoration, or tape based capacitor insulation, PET is also used as a photographic film, PET are widely used for fiber, paper with PET with material viscosity of PET is bottle films and fibers. Therefore, recycling is also slightly different.The factory waste production of PET films and fibers can be used for polyester / epoxy resin powder coating, generally the relative molecular mass of these scraps is about 20 thousand, above the melting point of 260 degrees, is composed of a single linear PET. This will use polyol alcoholysis waste at 250 to 260 degrees, can have a relative molecular mass of about 2000 to 5000 of the low melting point polyester oligomer. Oligomerization polyester was added at 200 to 220 degrees with two yuan anhydride and esterifying agent to obtain acid value of about 3. 05 mgKOH/g, softening point of about 85 to 105 degrees, glass temperature of less than or equal to 50 degrees of product, this product is used to make polyester / epoxy resin powder coating.

Q:What's the use of oil?

Some people have made such an estimate that 20 tons of oil can be mined worldwide every year. If only 2% of them are used as raw materials, they can produce 2 million 500 thousand tons to 3 million tons of protein, which can meet the nutritional needs of 200 million people for one year. At present, many countries in the world are researching and producing petroleum proteins.
